"The US authorities estimate that around 90% of the cocaine, which entered their country in 2006, transited the Mexico-Central America corridor. The amounts of cocaine trafficked into the United States declined, however, in 2006 and this trend became more pronounced in 2007 as Mexican authorities stepped up efforts to fight the drug cartels operating on their territory, which also increased the level of cocaine related violence in Mexico. US cocaine seizures along the country’s southern border declined by 20% over the first two quarters of 2007 on a year earlier and by almost 40% in the second quarter of 2007, as compared to the second quarter of 2006. The main entry point of cocaine into the United States continues to be the common border of Mexico with southern Texas (accounting for a third of all seizures along the border with Mexico in 2006), followed by the border with southern California (18%).14"
